Description

Knife type mowing device with grass shaking function

The technical field is as follows:

the utility model relates to an agricultural mechanical equipment field, in particular to sword formula grass cutting device with tremble grass function.

Background art:

the working mode of the knife type mower is a process of driving the transverse mowing knife to move along the ground surface through the locomotive to cut off weeds from the root position, and the knife type mower has the characteristics of high speed, high efficiency and smooth grass surface and is very widely used. However, such a mowing method has a drawback that when the weeds are cut off, the weeds are still in the original position, and when the weeds are thick, most of the cut weeds cannot fall down, even the cut straw breaks are still combined on the root-stem cutting openings. Under the condition, the vitality of part of weeds is relatively strong, and because the water supply of a cutting opening is not completely cut off and the vertical growth form is not influenced, the weeds cannot wither quickly, and survive and root after being maintained and risen. On the land with sufficient water, such as paddy field and forest, the water on the ground surface is sufficient, and the weeds which are not fallen down can root and survive again without long time under the supply of the water, so that the mowing operation becomes useless.

The biggest reason for this is that the whole grass body does not fall down or shift after the weeds are cut by the blades of the mower, and part of the roots of the weeds are adhered with soil, so that the growth conditions of the weeds are not changed seriously, and the weeds can continue to grow as long as water is supplied.

The invention content is as follows:

the utility model aims at solving the problem that weeds after the knife mower is cut off have secondary survival, providing a knife mower with tremble grass function, make weeds after cutting off lose survival chance.

In order to realize the technical purpose, the utility model discloses the technical scheme who adopts sets up at the cutting knife rear and raises the weeds that the grass tooth will cut off and pick up to the setting can the luffing motion tremble the tooth, tremble weeds and promote the soil block separation of weeds and adhesion after cutting off and expose subaerial completely.

The utility model discloses a knife-type grass cutting device with grass shaking function, which comprises a grass cutting mechanism, a grass shaking device fixing frame and a grass shaking device; the mowing mechanism consists of a cutter shaft, a fixing frame and a cutting knife, wherein the fixing frame is fixedly arranged at the upper end of the cutter shaft, and the cutting knife is fixedly arranged at the lower end of the cutter shaft along the transverse direction; the grass shaking device fixing frame comprises a chuck and a supporting plate, the grass shaking device fixing frame is fixedly arranged on the cutter shaft through the chuck, and the supporting plate is perpendicular to the cutter shaft; a shaft sleeve and grass raising teeth are uniformly distributed on a cutting knife of the mowing mechanism along a knife back; the grass shaking device comprises a power pump, an eccentric driving cam, a driving connecting rod and a shaking mechanism, wherein the shaking mechanism consists of a rotating shaft, a crank and shaking teeth; a rotating shaft of the shaking mechanism is arranged on a shaft sleeve of the cutting knife, a crank is fixedly arranged along the side end of the rotating shaft, and shaking teeth are uniformly and fixedly distributed along the axial direction of the rotating shaft; the power pump of the grass shaking device is fixedly arranged on the supporting plate, the eccentric driving cam is fixedly arranged at the output end of the power pump, one end of the driving connecting rod is hinged to the eccentric driving cam, the other end of the driving connecting rod is hinged to a crank of the shaking mechanism, the eccentric driving cam and the driving connecting rod form a crank connecting rod mechanism which drives the crank to swing in a reciprocating mode, the crank drives the rotating shaft to rotate in a reciprocating mode along the shaft sleeve, and the rotating shaft drives the shaking teeth to swing up and down in an angle mode along the rotating shaft.

The grass raising teeth are perpendicular to the cutting knife, one end of the grass raising teeth is fixedly arranged on the shaft sleeve, and the other end of the grass raising teeth is arranged along the knife face in a tilted mode towards the rear upper side.

The shaking teeth are perpendicular to the rotating shaft and are arranged in a staggered mode with the grass raising teeth.

The length of the shaking teeth is larger than that of the grass raising teeth.

The lowest position of the lower pendulum of the shaking teeth is lower than the position of the grass raising teeth, and the highest position of the upper pendulum is higher than the position of the grass raising teeth.

The driving connecting rod is arranged along the rear side of the cutter shaft and is vertical to the cutter.

The beneficial effects of the utility model reside in that: not only can the weeds cut by the cutting knife leave the ground completely and leave the primary growth position, but also the soil blocks adhered to the cut weeds are promoted to be separated from the roots and stems of the weeds, so that the weeds lose the chance of surviving again, and the mowing effect is improved.
